I can see a way out of this situation, a way which could be very simple to implement (and probably confusing to use). The question is if this solution is...

Is it really that? Anyone, including the original reporter, can set `perms = 0` (and perhaps also `dontchmod`), this is not related to #638. What I understand this issue to...

@powertoaster You are using a rather old version. Could you test again with latest Unison code (2.51.3rc1 at the moment)? How much available memory do you have on servers before...

As I had already built a test setup with 1.5 million files to investigate another issue, I gave it a go over a socket to try to reproduce this issue....

As I saw with my testing, while the overall root size can be very large without consuming huge amounts of memory, it is actually the number of updates to synchronize...

If think the maximum actual consumption I ended up with was 5 kB per file or even more. That could mean roughly 3-3.5 GB for 650,000 files. Just scanning the...

Thank you, @powertoaster. I think we have a confirmed issue now. 4 GB is most likely just not enough for roots of this size. @gdt I think you can remove...

@powertoaster there is one potential memory consumption fix in PR #402. If this scenario is still relevant to you and if you still have the possibility to test it, you...
